"Battle Beyond the Sun" is the 1962 Roger Cormanized version of "Nebo Zevyot" (The Heavens Beckon) from 1959. Corman had film student Francis Ford Coppola edit and dub the Soviet film, taking out specific cold war references and adding two absurd monsters to make it exploitable fare for US drive-ins. Later, for television release, an interchangeable bit of padding was added as a pre-credit sequence featuring "educational" footage of space models presumably filmed at an unknown aeronautical museum. This added about ten minutes to the running time and this same footage was used as pre-credit padding to the TV versions of other Corman Russian sci-fi epics. It's not present in this version.
